Uriginal application filed December 13, 1910, Serial No. 597,117. Divided and this application filed December 16, 1916. Serial No. 137,281.

To all whom it may concern:

Be it known that I, BURNHA-M 0. S110 NEY, a citizen of the United States, residing in Elizabeth, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Type-Writing Machines, of whichthe following is a specification.

This invention relates to typewriting machines, and more particularly to means for shifting the ribbon mechanism, so that different stripes or fields of the ribbon may be rendered inefiective. This application is a division of my application No. 597,117, filed December 13, 1910, (now Patent No. 1,237,258.)

I have provided that certain of the tabu- -lating keys for the typewriter carriage shall be capable of shiftingthe ribbon mechanism, so that the types shall print red, or any other special color.

The present improvements are illustrated in connection with column skipping, or column selecting keys, but it will e under stood that the invention ma be carried out in connection with other kinds of tabulating mechanism.

Other features and advantages will hereinafter appear.

In the accompanying drawings,

Figure 1 is a sectional side elevation of the forward portion of the tabulating key levers, showing one of the keys depressed and as having efi'ected a movement of the shifting ribbon mechanism to print on the red stripe or field of the ribbon.

Fig. 2 is a sectional side elevation of an Underwood typewriting machine with the ribbon mechanism set to print on the black stripe or field. I

Fig. 3 is a part sectional rear elevatlon of the typewriting and tabulating mechanisms.

In the Underwood machine, keys 1 depress levers 2 to vibrate bell cranks 3, and swing type bars 4 up to strike rearwardly against the front side of a platen 5. Said platen is mounted on a carriage 6, running on tracks 7, 8, and is driven by a spring barrel 9, and also has a rack 10 meshing with a pinion 11 connected to an escapement wheel 12, the escapement dogs being seen at 12 The rack 10 is hung on arms 13, so that it may be lifted from the pinion 11 to release the carriage.

Tabulator keys 14 are mounted upon levers 15, which, at their rear ends, raise stoprods 16, having stops 17 at their upper ends. These stops may cooperate with interchangeablyadjustable column stops 18, inserted, as required, in notches 19, 20, formed in the top and bottom of a bar 21, which is fixed to the carriage 6.

Each stop-rod has a shoulder 22 cooperating with a universal bar 23, which rocks about a pivot 24, and has an arm 25, which draws down a link 26 and vibrates a lever 27, the latter fulcrumed at 27 and carrying a roll 27 to run upon the under side of the rack bar 10, and lift the latter from the escapement pinion 11, whenever a key 1 1 is depressed.

In the present instance each of the tabulatlng keys 14 is a column-selecting key, and, when depressed, serves to bring the carriage 6 to a predetermined column. One manner of effecting this kind of tabulating consists in having the stop-rods 16 of assorted lengths, and having the column stops 18 of assorted depths, so that, the strokes of the stop-rod being uniform, each rod cooperates with its associated stop, regardless of the posltion of the latter along the rack. The

first stop-rod 16 in the series (the rod at the The connection between the tabulating keys and the ribbon mechanism, which will hereinafter. be explained, comprises a horizontal rock-shaft 80, extending across the machine beneath the tabulating key levers 15 and forward of the fulcrum 81 of the latter and suitably supported upon the framework. This rock-shaft 80 may be rocked by means of forward and rear universal bars 82, 83, fixed upon the two pairs of arms 84, 85, extending forwardly and rearwardly from the ends of said rock-shaft, the whole making a rocking frame.

Certain of the tabulating key levers 15 have downwardly extending projections or toes 86 forward of the rock-shaft 80 and overlying the universal bar 82, so that when any one of said certain keys is depressed, the rocking frame is rocked to the position seen at Fig. 1. Certain other of the tabulating key levers 15 are provided in rear'of the rock-shaft 80-with downwardly extending projections 102 to depress the universal bar 83 and turn the entire rocking universal bar or frame to the position seen at Fig. 2.

The usual bichrome ribbon mechanism of an Underwood typewriting machine comprises a universal bar 108 operated by heels 109 of the type bars and connected to the dogs 12 which feed the paper carriage 6. Upon said universal baris fixed a bracket 110 which carries a slotted actuator 111 to engage one of two wrists 112, 113, upon a lever 114, to whichis pivoted an upstanding ribbon carrier 115- in front of the platen. The actuator 111 is usually two-armed, and by shifting the same on the bracket 110, the actuator is moved alternately into and out of engagement with one or the other of the Wrists 112 and 113 on the levers 114. This shifting of the actuator 111 is usually efi'ected by a link 116 pivoted at 117 to an arm 118 extending up from a horizontal rock-shaft 119 which extends forwardly and carries at its forward end a two-armed lever 120 having keys 121, 122, and also having a detent 123 to engage a V-spring 124, whereby the lever is held in position. The keys 121 and 122 are able to be effective because of the lost motion of the tabulator key levers 15 before their lugsstrike the universal bars 82, 83.

To this bichrome mechanism is connected a link 125, the latter having at its upper end a slot 126 to engage a pin 127 upon the lever 120. The link is pivoted at its lower end at 128 to an arm 129 fixed upon the rockshaft 80.

When the parts are in the position seen at 7 Figs. 2 and 3, the ribbon mechanism is in position to expose the black stripe of the ribbon to the action of the types; the actuator or yoke 111 being connected to the upper wrist 112; but when any tabulator key with a projection or toe 86 is depressed, as at Fig. 1, the link 125 is thrust up, thus rocking the lever 120 and the rockshaft 119, and vibrating the arm 118 through the link 116, shifting the actuator 111 so that the lower wrist 113 is connected to said actuator, and thus the lever 114 is vibrated at each stroke enough to .carry up the red or special stripe of ribbon to be struck by the yp $n After depressing and releasing any tabulating key 14, the rocking frame 82, 83, etc., of course, remains in the position to which it has been set'by said key, and until another tabulating key is operated, unless a key 121 or 122, as the case may be, is operated; but,

of course, the invention is not limited to a tabulating mechanism of. this character and operation. 7
